find_startup_dir() returns an index, not a bool.

Allow a section to stop the install process by setting done=true
or be the last of its install-type by setting last=true.
These changes allow us to prompt whether to use remote JSON-db servers
(e.g. bbs.electronicchicken.com) or to install/enable the JSON-db
service locally, based on the sysop's choice.

("Cats" list) make it a simple confirmation to choose it as the install
location.

This makes the config files more portable/migratable.

for the json-service.ini "dir" key. The code that parses that value is not
very tolerant of the absence of a trailing slash.

logoff for the server to recycle and changes to take effect.

theory at least) and "jsexec -C" could be used to execute this script. Maybe.

Request sbbs recycle after completing install(s).

Inherit the "name" value from the root section in the install item sections.

- Name (name of the program)
- Desc (description)
- From (the 'By' line for author/programmer/publisher)
- Cats (comma-separated list of applicable categories (e.g. "Games")
- Subs (comma-separated list of applicable sub-categories (e.g. "Adventure")
- Inst (Installer .ini file source/revision/author/date info)

being installed (free-form text, up to 79 chars for pretty-print).
Remove the "requires_service" key, replaced with:
Add ability to install/update services.
Add ability to add/update sections in .ini files with eval()'d key values.
This allows the json-service dependant scripts to (mostly) be installable
under all scenarios. tw2.js is still an exception.

"JSON") that must be installed and enabled for the external program to be
installed. This is inteded for use by the various .js "doors" that rely on
json-service.js to function. If the specified service isn't installed and
enabled, the install won't continue.

Support the new "-auto" command-line option to automatically scan xtrn/* for
uninstalled install-xtrn.ini files.
I intend to have this a stock Operater extenral program so the sysop can just
cvs-update or download an extract to extern and then run the external program
(with the -auto option) to automatically find and install the program.

function (using function.apply()) rather than depending on the js.exec()
array-args-expansion feature I recently added and then just removed.

overwrite of existing items (i.e. programs with the same internal code).
Add support for [exec:<file>.js] sections: for executing another JavaScript
files as part of the install.
Add support for [eval:string] sections: for evaluating a JavaScript expression
as part of an install.
Add support for an optional "prompt" key for each item. If set to a string,
overrides the default confirmation prompt text. If set to false, disables
the confirmation prompt for that item.

script itself contains the current documentation for developers to make use
of it and make it super easy for sysops to install their programs into their
Synchronet systems.
